Towards a traceable nanoscale force standard

摘要: The National Institute of Standards and Technology has launched a five-year project to traceably link the International System of Units (SI) to forces between 10-8 N and 10-2 N. In this paper, we give a background and overview of this project, discuss the electrostatic realization and dissemination of force through a mechanical balance, and provide a brief summary of the Microforce Laboratory being constructed at NIST.
